vercd with hand-glasses, which, in the middle 

 of summer, answer well, but in the spring or 

 autumn the former method is preferable. After 

 planting, the glasses should be shaded in the 

 heat of the day, and the slips frequently re- 

 freshed with water, but not given them too libe- 

 rally, as much wet rots them. When they have 

 got strong roots they should be planted separately 

 in small pots filled with fresh light earth, and 

 placed in a shady situation till fresh rooted, when 

 they may be placed in the open air, in a sheltered 

 situation, till autumn, and then removed into a 

 dry airy glass-case, or green-house, for the win- 

 ter season, or under a common hot-bed frame, 

 as they only require protection from frost and 

 wet. 



The sixth species may be easily propagated by 

 cuttings, which should be planted in summer in a 

 shady border, or be shaded with mats in the heat 

 of the day: when they have stricken good root 

 they may be carefully taken up, put into separate 

 pots filled with light, poor, sandy earth, and placed 

 in the shade till again well rooted ; then put with 

 other hardy exotics in a sheltered situation till 

 frosts appear, when they should be removed into 

 the green-house, placing them so as to have free 

 air. 



The single-flowered common sorts are mostly 

 cultivated as pot-herbs for the use of the flowers 

 in broths, or as ornamental plants for the beauty 

 of their flowers, which effect an agreeable diver- 

 sity in the common borders of pleasure-grounds, 

 in assemblage with other hardy annuals ; and 

 the third and fourth species may be made use of 

 in the same way. 



The two last sorts, from their continuing long 

 in flower, also afford much variety when set out 

 with other potted plants in the summer, and in 

 the green-house in winter. 



CALF's-SNOUT. See Antirrhinum. 



CALLA, a genus containing a plant of the 

 herbaceous flowery perennial green-house kind. 

 ./Ethiopian Arum. 



It belongs to the class and order Gynandria 

 Polyandria, and ranks in the natural order of 

 Piperita?. 



The characters are: that the calyx is a one- 

 leafed spathe, ovate- cordate acuminate, coloured 

 at top, very large spreading, permanent: the 

 spadix finger-shaped, quite single, erect, co- 

 vered with fructifications: there is no corolla: 

 the stamina consist of some filaments inter- 

 mixed with the germs the length of the pistils, 

 permanent, compressed, truncate: the anthers 

 are simple, truncate, and sessile: the pistil- 

 lum to each is a roundish obtuse germ : the 

 style simple, very short : the stigma acute: the 

 pericarpium contains as many berries as there 



are pistils, four-cornered, globular, pulpy, and 

 one-celled (several-celled) : the seeds numerous 

 (six to twelve), solitary, oblong, cylindric, and 

 obtuse at both ends. 



The species cultivated for ornament is C. 

 ^■Et/tiopica, ^Ethiopian Arum, or Sweet Calla. 



It has thick, fleshy, tuberous roots, which arc 

 covered with a thin brown skin, and strike down 

 many strong fleshy fibres into the ground. The 

 leaves arise in clusters, having foot-stalks more 

 than a foot long, which are green and succulent : 

 the leaves are eight or nine inches in length, and 

 of a shining green, ending in a sharp point, 

 which turns backward: between the leaves comes 

 out the scape, which is thick, smooth, of the 

 same colour as the leaves, rising above them, and 

 terminated by a single flower shaped like those 

 of the arum: the hood or spathe is twisted at 

 the bottom, but spreads open at the top, and is 

 of a pure white colour. In the centre of this 

 is situated the spadix or club, which is of an 

 herbaceous yellow colour, upon which the small 

 herbaceous flowers are closely placed ; it is only 

 about half the length of the spathe ; it is suc- 

 ceeded by roundish red berries. It is a native of 

 the Cape. 



Culture. — This plant i3 readily increased by 

 offsets from the root, which should be separated 

 in the autumn, and planted out singly in pots of 

 light earth, where they become full plants the 

 following year. The plants may be kept in the 

 full air during the summer, but during the win- 

 ter should have the protection of the green-house 

 or a garden-frame. 



These plants, from the singularity of (heir 

 growth, and their being constantly furnished 

 with leaves, have an agreeable effect, and 

 produce much variety among other potted 

 plants. 



CALLICARPA, a genus containing a plant 

 of the deciduous flowering shrubby kind. 



It belongs to the class and order Tetrandria 

 Monogynia, and ranks in the natural order of 

 Dumosce. 



The characters of which are: that the calyx 

 is a one-leafed perianthium, bell-form: mouth 

 four-cleft and erect : the corolla is monopetalous, 

 tubular: border four-cleft, obtuse, spreading : 

 the stamina consist of four filiform filaments, 

 twice the length of the corolla : the anthers are 

 ovate and incumbent : the pistillum is a roundish 

 germ: the style filiform, thicker at top: the 

 stigma thickish and obtuse : the pericarpium is 

 a globular berry, smooth : the seeds four, ob- 

 long, shaped like a meniscus, compressed, cal- 

 lous. 



The only species cultivated is the C. Ameri- 

 cana.
